Plain English Summary

AI-GENERATED
Mandates estimated tax display on all online residential property listings.

Online platforms must now display estimated ad valorem taxes for every residential property listing in Florida. This requirement applies to websites, web apps, and mobile apps, but excludes social media platforms.

Platforms must calculate estimates using the listing price and current millage rates. They are strictly prohibited from using the current owner's actual tax bill to generate these forward-looking estimates.

The Department of Revenue must publish a calculation formula and countywide average millage rates annually. These tools allow platforms to meet the new disclosure requirements without relying on individual property tax histories.

Platforms are protected from lawsuits if their tax estimates are inaccurate. This immunity applies to any person involved in the estimation process, provided the required disclaimers are displayed alongside the figures.
